The good: A quick, agile guard, Grubbs earned first-team All-SEC honors over his final season while finishing with 38 consecutive starts. An aggressive blocker, he shows good footwork and fine functional strength to grade out high in many areas of play. He is quick on the snap and gets into a defender nicely with the hand technique to steer and control him the full play. He is effective in space and can make contact consistently in the open field with the ability to finish each block.

The bad: While he has good size and arm length that helps his effectiveness against big defensive tackles, he is not a road-grader. Also needs to show a nasty demeanor and temperament to challenge for starting time at the next level. Grubbs occasionally will struggle when he is matched up against top speed rushers or against bigger defenders when he plays too tall and allows a defender to get into his body.

Outlook: Tough, durable prospect with very good fundamentals and level of development to start as a rookie. He is a marginal top 50 prospect on our board, but his level of development may earn him a surprise first-round selection.
